I was on the bus today when this one guy came on and repeatedly failed to deposit a coin in the machine.
The guy said he didn't know that the bus, which was in America, didn't take non-American coins.
The bus driver, who was pretty pissed off and seemed like she hated her job, chucked the coin to the window and announced, "For those of you who don't know, we only take American currency. The machines are designed to filter out foreign currencies. We don't take $2 coins, pesos, or Chuck E Cheese [coins]."
